No mess, no fuss...

 With the H2O client's unique operating system the effort is removed from bulk water sales.  No key cards or coins, no difficult maintence or unreadable reports.  The H2O client provides a city or industrial entity with access to a operator friendly, low maintainence system which clearly and consistenly monitors water sales.  Providing customers with an ability to pre - purchase their water or pay as they go and owners with data on who is purchasing water, how much water they purchased, and comparing these numbers with previous amounts.  All this is accomplished with the entrance of a simple pin code which can be made by the customer.  The H2O client was designed to simplify bulk water sales, while providing valuable data to cities or industrial entities which allow these entities to better provide water or create a larger market.
